SAP Handheld Devices are solutions that speed up warehouse processes and minimize errors. Traditionally powered by RF (Radio Frequency) technology, these devices now connect to the SAP system via SAP ITS Mobile, enabling warehouse operations to be managed directly through mobile devices.
In this article, we will explore SAP MM and SAP WM modules, focusing on stock transfers, bin-to-bin movements, and the benefits of using ITS Mobile.
What is SAP ITS Mobile?
SAP ITS (Internet Transaction Server) Mobile is a technology that allows SAP RF screens to run in a mobile web browser.
-
RF screens are converted into HTML-based interfaces.
-
Handheld devices, smartphones, or industrial mobile devices can access SAP.
-
No additional software installation is required – it runs directly on a browser.
With ITS Mobile, warehouse operations can be managed easily, anytime, anywhere.
